Detailed explanation-1: -Random Errors Human errors involve such things as miscalculations in analyzing data, the incorrect reading of an instrument, or a personal bias in assuming that particular readings are more reliable than others.
Detailed explanation-2: -Random error is also known as variability, random variation, or ‘noise in the system’. The heterogeneity in the human population leads to relatively large random variation in clinical trials. Systematic error or bias refers to deviations that are not due to chance alone.
Detailed explanation-3: -Reaction time – If your experiment involves timing with a stopwatch for example, the speed at which you stop the timing may affect how close to the true value the experimental measurement is. As you may have different reaction times with each round of the experiment, this is a random error.
Detailed explanation-4: -Due to the presence of random variation, it can be difficult to determine whether or not all of the data in a data set are of equal quality.
